Plastic scintillators have the advantages of fast time response, low cost, high light output, and sensitivity to X-rays, gamma-rays, alpha-rays, beta-rays, and fast neutrons. These plastic scintillator materials also have excellent durability, and by mold and other methods, they can be made into almost any shape you want, including cast sheets, blocks, rods, cylinders, and thin films. Plastic scintillators are now widely used in a broad range of radiation detection applications.
